현재의 이동통신시장은 시장의 포화상태로 인해 신규 고객의 확보보다는 기존 고객의 유지에 마케팅 활동을 강화하고 있다. 본 연구에서는 이탈고객관리(churn management)를 위한 방안으로 데이터마이닝 기법에 기반하여 고객을 등급별로 세분화하였다. 이동통신 고객데이터를 활용하여 로짓모형, 인공신경망, SVM 등을 이탈고객 예측모형을 개발하였고, 각 모형별 성과를 통계적으로 비교하였다. 이탈고객 예측모형을 통해 고객의 이탈가능성을 등급화하여 등급별 이탈확률과 점유율, 적중률을 산출하였다. 제안된 고객등급화 방법을 통해 이동통신사들은 고객의 이탈확률에 따른 차별화된 마케팅 전락을 수행할 수 있을 것으로 기대된다.

The study focuses on the ICT industry, which is considered future growth engine. Tthe main objective of the research is to examine the extent of the competitiveness of the Chinese ICT industry, which is rapidly emerging as a competitor of the ICT industry in Korea. The ICT items subject to primary analysis of this study were computer and peripherals items. Analysis methods used were MSI (Market Share Index), EBI (Export Bias Index), and MCA (Market Comparative Advantage). The analysis period was from 2008 to 2016, and the analysis dater used were the export-import data provided by KITA. According to the study, Korean market share of Chinese computers and peripherals items has continued to increase, exports concentrated on the Korean market are intensifying, though the degree of competitiveness gained by the Korean market is quite strong. In particular, 852851, 847160 items have the largest competitiveness in the Korean market compared to other items used in this study. The implications of this study for the Korean market are as follows: i) improvement of quality with price ii) convergence product development between computer and peripherals items and consumer -friendly design development, and iii) marketing efforts to improve product awareness so that consumers recognize Korean computer and peripherals products.

This paper aims to analyze comparing the international competitiveness of Korea and China of ICT 10 goods in ASEAN Big 6 countries.(Malaysia, Indonesia, Vietnam, Singapore, Thailand, Philippines). In this study, we investigate major trends in Korea's ICT goods through various data analysis and evaluate. From 2009 to 2016, As analyzed by ESI, CTB, and EMS, This paper showed Korea has increased its export, EMS and Export Competitiveness to ASEAN. However, due to rapid imports, the trade balance deteriorated and ESI decreased. China showed signs of improvement in international competitiveness, although exports, ESI and EMS were declining. Compared to South Korea, China has seen less export bias to ASEAN. ASEAN is becoming an increasingly important trade partner in Korea's ICT exporting. This paper points out several policy implications drawn from its analyses and findings.

구글의 안드로이드 플랫폼은 오픈 소스의 특성으로 인해 스마트 폰 제조사와 통신 사업자, 일반 사용자들의 많은 관심을 받고 있으며 2013년 2분기에는 전 세계 스마트 폰 시장에서 점유율 79.3%라는 결과를 얻게 되었다. 하지만 안드로이드의 높은 점유율만큼 안드로이드 플랫폼에 대한 공격들 또한 많아지고 있다. 이러한 공격들로부터 안드로이드 플랫폼의 보안성을 향상시키기 위해 많은 보안 기능들이 안드로이드에 탑재되고 개선되고 있지만, 보안 기능이 개선되는 만큼 새로운 보안 취약성들도 발견되고 있다. 본 연구에서는 안드로이드에서 제공하는 응용 프로그램 권한 기법에 대한 보안 취약성을 분석하고 그에 대한 향상된 보안 대책을 제안한다.

This paper is to estimate the market potentiality of ubiquitous health(u-health) from a viewpoint of communication companies. For this estimation, we used the CVM and adopted the ratio of ovum(2000) in overall market of u-health. That is, firstly, we assumed the u-business model was based on mobile business approach. Through this estimation, we conclude that communication companies at the initial stage of the u-health market can continuously promote the market share ratio via strategic alliance with the players participating.

This paper shows that when the exchange rate changes, there are conflicting effects on improving the quality and increasing market share of eco-friendly vehicles. In a vertically differentiated duopoly model consisting of high quality clean cars and low quality internal combustion engine cars, I set up a two-stage noncooperative game under perfect information that the quality levels and the prices of the cars are competitively determined. The vehicles are assumed to be produced in countries that use distinct currencies. When the exchange rate of the country that produces low quality cars rises, the producer prefers to intensify competition due to the relatively lowed cost, and the incentive for quality improvement arises from the intension of attempting to reduce the degree of differentiation of quality level. At this time, the clean car manufacturing firm tries to avoid competition due to weakened competitiveness, and increases the quality level to expand quality differentiation. However, in this case, the market share of eco-friendly vehicles shrinks. On the other hand, if the exchange rate changes in the opposite direction, the market share of eco-friendly vehicles is expected to increase, but the quality of both cars are deteriorated, causing a conflict effect.

31년 전 창업한 디지틀 이큅먼트사(DEC)는 연간 매출고 1백억 달러에 이익 10억 달러를 올리는 컴퓨터계의 제2인자가 되었다. DEC는 IBM에 비해 규모는 6분의 1에 지나지 않지만 지난 20년대 이 '정보산업의 거인'IBM의 가장 두려운 도전자의 자리를 지켜왔다. 그래서 업계에서는 DEC를 골리앗IBM에 대항하는 '다윗'으로 비유하고 있다. DEC의 매출고는 1984년이래 중형 컴퓨터인 백스 미니컴퓨터의 큰 성공에 힘입어 불과 4년간에 2배로 급증했다. 대당 1만 5천 달러에서 70만 달러의 이 중형 컴퓨터시장에서 DEC의 시장점유율은 1984년의 19%에서 현재 25%으로 뛰어올랐으나 IBM은 24%에서 16%로 오히려 줄어들었다.
